American statesman, born at Boston; was bred to the bar, and entered Congress in 1804, where he distinguished himself by his oratory as leader of the Federal party, as the sworn foe of slave-holding, and as an opponent of the admission of the Western States into the Union; in 1812 he retired from Congress, gave himself for a time to purely local affairs in Massachusetts, and at length to literary labors, editing his speeches for one thing, without ceasing to interest himself in the anti-slavery movement (1772-1864).
